But when in the meantime of delivery that file is deleted, lmtp fails to deliver the message to remaining mailboxes. For example a message for 46 recipients is delivered by lmtp to the first 12 only (fortunately postfix retries delivery for remaining recipients) and for the rest lmtp logs the following error messages:
